Description

Technical Field

[0001] The utility model relates to the technical field of deep foundation pit monitoring, in particular to a novel deep foundation pit monitoring device. Background Art

[0002] Foundation pit monitoring refers to the inspection and monitoring of the building foundation pit and the surrounding environment during the construction and use period. Foundation pit monitoring mainly includes: supporting structure, related natural environment, construction conditions, groundwater conditions, foundation pit bottom and surrounding soil, surrounding buildings, surrounding underground pipelines and underground facilities, surrounding important roads and other objects that should be monitored.

[0003] For example, a deep foundation pit monitoring device with Chinese patent number CN218001060U, in which a lifting mechanism and a rotating mechanism are set up so that the lifting seat moves up and down alternately during the rotation of the double-threaded screw, and the back-and-forth movement of the rack drives the gear to rotate, so that the camera at the upper end of the rotating shaft can perform all-round monitoring. However, this design method requires the device to be placed inside the foundation pit for monitoring, which increases the complexity of use. At the same time, the camera structure is kept in a flat state during the adjustment process, resulting in the inability to monitor lower-level parts such as the bottom wall and side inner wall of the foundation pit, further reducing the convenience of use. Therefore, a new deep foundation pit monitoring device is proposed to solve the above problems. Utility Model Content

To ensure the compatibility of the equipment, the operating methods used are consistent with the parameters of marketed equipment. The description here is not admitted to be prior art because it is included in this section.

[0029] When implementing, follow these steps:

[0030] 1) First, the piston of the electric telescopic rod 3 is started to extend downward, so that the camera 405 descends downward along the opening of the deep foundation pit, thereby monitoring the internal environment of the deep foundation pit;

[0031] 2) Then, the output shaft of the reduction motor 401 is started to rotate, driving the mounting base 402 to rotate the camera 405 in an arc motion, thereby adjusting the camera monitoring range horizontally to the left and right;
